Specification of Letters Patent.

Application filed January 21, 1915. Serial No. 3,567.

To all whom it may concern Be it known that I, ADoLF DANGL, subject ofthe Emperor of Austria-Hungary, and resident of 25 Lowengasse, ViennaIII, in the Empire of Austria-Hungary, have invented certain new anduseful Improvements in Methods for Covering Rings with Threads, of whichthe following is a de scription.

The present invention relates to a method for covering rings, especiallywire rings destined for linen buttons with a single thread in such amanner that the same may not be drawn open and that the ring body issurrounded in its cross-section by the thread and may also be coveredwith thread sections running radially or lying in chords to thecircumference of the ring.

In the known methods for covering rings with a thread the thread ispassed around the ring so as to form a loop and the thread is drawnthrough said loop so as to lock it. The loop is thereby formed in theknown methods at that side of the ring which is turned away from thepath of the shuttle so that the loop must be passed around the ring tocome within the reach of the shuttle. This movement is effected bytransmitting the loop which-has been drawn out by meansof a needleprovided with a hook to a holding member which is movable into the pathof the needle and of the shuttle, said member carrying the loop aroundthe ring body and back to the path of the shuttle whereafter the threadof the shuttle is passed through the loop. Another method consists incatching the loop by means of a second hook of a needle provided withtwo hooks and drawing it at the outside of the ring after a lat eralmovement of the latter into the path of the shuttle so as to enablelocking.

According to the present invention and in contrast with the two knownmethods above referred to the loop is formed at that side of the ringwhich is turned to the path of the shuttle so that the shuttle maydirectly pass through the loop for locking it. In this method the loopis not turned around the ring but is drawn tight at the same place whereit has been formed, while the running thread is laid around the ringwhen the shuttle passes through the loop. In this manner covering of thering with thread is very simple in comparison with the known methodsabove referred to.

If it is desired to produce, by meansof the single thread covering thecross-section of the ring, spun rings, that is to say to cover also theopening of the ring with radial or spoke-like thread sections, themethod is carried out in such a manner that the ring body is sewn aroundone or several times at one point with thethread as stated herein beforeand that the thread is then passed across the opening of the ring forcovering the body thereof at the opposite part in the same manner bysewing it one or several times around the body of the ring, whereafterit is returned to the initial point to be there sewn again around at theside of the first windings, which procedure is repeated until the ringis wholly sewn and spun. Since the needle forming the loop is situatedat the same side of the ring'as the shuttle so as to be able to draw theloop to said side, it is necessary to draw the thread at the other sideof the ring that is to say at the side which is turned away from thepath of the shuttle, in order to obtain at this side a thread sectionbridging the ring opening partly or wholly and extending within thereach of the needle so as to permit formation of the loop, said sectionbeing caught by the hook of the needle which passes through the openingof the ring and draws the loop to the side of the shuttle which travelsthrough the loop for looking it. If in the manufacture of spun linenbuttons, the ring opening is also to be covered with thread sections thethread is alternatively carried from the one and the opposite sideacross the opening of the ring and is drawn by the hook of the needleinto the path of the shuttle which in its to-and-fro movement forms thethread sections covering the opening ofthe ring which are then locked bythe loops running home after the shuttle has been passed therethrough.When forming a button with sections covering the opening of the ring,the ring may also, after having been sewn around at a point one orseveral times, be turned one or several times around an axis which issituated perpendicularly to the running thread so as to form severalthread sections covering the opening, the last of said sections at theside opposite to the hook being used for forming the loop.

In the accompanying drawings Figures 112 are representing the severalsteps of the method as it is carried out by drawing a thread section soas to bridge the opening of the ring and to enable the formation of ingthe opening thereof and being produced plan view of a ring produced bythis methodform a loop (Fig, at).

by said method. Fig. 1st is a plan view of a spun ring which ismanufactured by the same method and is provided with parallel threadlayers covering the opening thereof.

Figs. 1517 inclusive are representing a modified form of execution ofthe method;

Figs. 18 and 19 show a spun ring produced by this method in plan Viewand cross-section, respectively; Figs. '2033 represent the abovereferred to method in which the thread section serving to form the loopis obtained by tilting the ring; Fig. an is the and Fig. 35 shows amodification.

For carrying the method into practice the ring 1 is covered with athread by sewing or spinning by means of a hooked needle 2 and a shuttle8, crossing the path of the needle and traveling across the opening ofthe ring. YVliile in the known methods the path of the shuttle issituated at the side ofthe ring which is remote from the needle, theshuttle according to the present invention is traveling at the side ofthe ring facing the needle so that the running thread isdrawn across thering at the side facing the needle? (Fig. 1). If the shuttle has reachedone of its two end positions, a guide 5 which is arranged beneath thepath of the shuttle and which is oscillating around the ring takes thethread and assisted by the tightener 6 draws the same below the ring 1so as to form a looped section bridging its opening (Fig. 2). In thefollowing progressive movement of the needle 2 the same passes throughthe opening'of the ring (Fig. 3), catches the upper part of the threadsection passing around the guide 5 and bridging the opening ofthe ring,drawing said section on its return stroke into the path of the shuttleso as to Now the shuttle passes in its movement to the right hand side(Figs. 5 and 6) thro 'h the loop, whereupon the thread isslipped off theguide and h h els oi he edl 50 t a on th f lowing hand stroke of theshuttle the loop tightens under the action of a second ti 'htener 6" andlocked to the ring body For the purpose, of covering the open ng of thering "with thread layers which are arranged radially or parallel to adiameter-the ring is now turned in its p an 9 shif d r eree el h aextent equal to the of two layers or sections and the operation isrepeated at the opposite side of'the ring. A second guide 5"'provided atthat side of the ring draws hetehrth t ree hel the op ni o t es(Fig-p8), and th up er S i n o s raf s are p t term a e r e i s withinthe path of the shuttle (Figs. 9 and 10) so that the shuttle in itsreturn movesaid loop (Fig. 11) and the loop after having left the guideand the needle is drawn tight under the action of the tightener 6 (Fig.12). The ring is then again turned or displaced and the thread iscarried around the left hand side of the ring as already described,until the ring is wholly covered with the thread. Owing to the fact thatthe thread is tightened and bound to the body of the ring alternativelyat opposite sides of the ring during the reciprocating movement of theshuttle, the ring is covered in its step wise turning movement withradial thread sections 7 as shown in Fig. 13 or with parallel saidlayers or sections being fastened to alternating sides of the ring bymeans of the loops 8. The thread layers covering the opening of the ringare thereby arranged at one face and the loops at the other face thereof(Figs. 13 and 14;).

In order to facilitate entering of the shuttle into the loop the samemay be tilted sections '7 as shown in Fig. 1% when it is 1 displacedsidewise instead of being rotated,

by means of the hooked needle by turning the same around its axis to anangle of about is crossed and opened toward the path of the shuttle soas to avoid misses. Besides, turning of the needle has the effect thatthe hook takes only the branch of the thread position indicated in Fig.15 so that on passing of the shuttle through theloop (Fig. 16) and onsubsequently tightening the loop the same is tied into a knot with therunning thread 4; (Fig. 17) In this manner the single sections or layers'7, 7 of the thread covering the opening of the ring are held firmly/inposition (Figs. 18 and19),

. and loosening of the windings covering the ring body as it occurs incoverings made according to the known methods, is prevented effectively.7

"The manufacture of covered rings by sewing and spinning threads aroundrings of wire or the like may also be effected with the use of knots asmentioned hereinbefore, in the following manner.

If the thread has been fined at one place of the ring body 1, forexample at b and the running thread 4 has been stretched above asindicated in Figs. 4-6 so that the loop the opening of the ring, theshuttle 3 being a lrnot at 7) (Fig. 27).

situated at this moment at the left hand' side of the ring 1 remote fromb (Fig. 20), fthe" ring is turned in the direction of the arrow throughan angle of 180 in such a manner that the thread t passesaround theringas' indicated in Fig. 21. Thenthe shuttle moves into its other endposition so that the thread stretched beneath the ring is free to be"caught by the hook ofthe needle '2 (Fig.

The needle passing through the open ing of; the ring takes the thread(Fig. 23)

and draws it upward to form the loop (Fig. l

which after having been twisted (Fig. 2-5) is traversed by the shuttle 3returning to the left hand side (Fig; 26) the loop bein g therebytightened under the coaction of the tightener 6 which moves in adirection opposite to the direction of movement of the shuttle so thatthe loop is knotted at a place a of the ring body opposite to thepreceding The shuttle is now again in its initial. position as in Fig.20 but the thread 4 crossing the opening of the ring is twisted (Fig.31') and traversed by the.

shuttle 3 returning to the left hand side (Fig. 32). The loop afterbeing released from the needle is tightened under the coac tion of thetightener 6 (Fig. 33) and is knotted at the place I) of the ring 1- opposite to the place a where the last loop has been knotted. Then the ringis againgturned and the operations are repeated as describedhereinbefore until the ring is wholly wound and covered with thread. Inthis manner the ring isprovided with a covering formed by a singlethread which covering has in distinction from coverings formed-by theknown methods no loops which are passed around the ring. lhe ring whichis rotated or displaced intermittently or stepwise in its plane andturned about a diameter perpendicular to the path of the shuttle is onlyspun with radial or parallel threads which are knotted alternatively atopposite sides of the The covering of the ring may, howring. ever, alsobe executed, if desired, by turning the ring through an angle of twiceor more times 180 whereafter the thread is knotted. In this manner thering is provided with one or more unknotted thread sections 10 (Fig.between the knotted sections 7.
